Application December 17, 1954, Serial No. 476,005

1 Claim. (Cl. 222--23) My invention relates to a dispensing device forliquids and it is an object of the same to provide a device of thecharacter described, which shall be simple and constructed of few partsand which can readily be applied to a container or removed therefrom,which shall be capable of dispensing the contents of the containerpractically completely, and which may be made at small cost, yet shalloperate effectively and simply. Liquids can be dispensed by the use ofthis device, in quantities as desired and with little waste of material,and the device may be discarded after emptying a container, with littleloss by reason of the cheap and simple construction of the device.

Referring to the drawings, in which similar parts are designated bysimilar reference characters.

Fig. l is an elevation of the device of my invention,

Fig. 2, a view of the upper portions of Fig. 1, but differentlypositioned, and viewed from the right in Fig. 1,

Fig. 3, a part sectional view on line 3-3 of Fig. 2 in the plane of thepaper as seen in Fig. 1,

Fig. 4, a section on line 4-4 of Fig. 3,

Fig. 5, a section on line 55 of Fig. 3, and

Fig. 6, a detail of a valve.

In the drawings, reference character indicates a container of anypreferred character and material, on which a cap 11 is mounted, as byscrew threads indicated at 12. A tube 13 leads from a point close to thebottom of the container, as shown in Fig. 1, to the cap 11, to which itis attached at 14 in any convenient manner so as to provide a tightjoint between the pipe and the cap. An outlet pipe 18 is connected tothe cap by means of screw threads 15, and a valve 17 having a handle 19is positioned between the cap 11 and the end of the pipe 18 to controlthe exit of fluid from the pipe. Pressure is created to act on thecontents of the container 10 by means of a conventional bulb or bellows21 having a check valved opening 21, this bellows pumping air into thecontainer as indicated by arrows leading from the bellows through a pipe22 and a passage 23 in the head of the container, the end of the passagebeing shown as closed by a resilient cap 25 fitting on a nipple 26.

This cap, which is best shown in Fig. 5, has a resilient Patented Sept.23, 1958 ICC gasket 28 which seals against the container 10 and also hasan end closure of thin rubber in the shape of a tube flattened atopposite sides at 29, and provided with a slit 27 at its lower end, theslit being normally closed due to the resiliency of the rubber so as toprevent air from escaping from container 10 and returning to the bulb,thus forcing liquid in reverse direction back toward the bellows 21,while permitting fluid in container 10 to be forced by air pressurethrough pipe 13 and out through pipe 18. 0

The cap 11 is provided with a passage 31 through which air may be forcedfrom the container into an inflatable and expandable member 30 by a bulb21 to cause expansion of the member 30 by air pressure. The member 30then serves as an indicator of the amount of pressure by the extent ofexpansion. It also serves as a safety device in that it will be rupturedby excessive pressure due to the heating of its contents or for otherreasons.

Upon opening the passage leading to outlet pipe 18 the valve 17 willpermit escape of air to whatever receptacle may be connected to outletpipe 18, or into any fluent mass to which said pipe leads, as well as topermit escape of liquid in the container 10 to be forced by air pressurethrough pipe 13 to pipe 18.

It will be obvious to those skilled in the art that many changes may bemade in the devices of my invention, all without departing from thespirit of the invention, and therefore I do not limit myself to what isshown in the drawings and described in the specification, but only asindicated in the appended claim.

Having thus fully described my invention, what I claim is:

A dispensing device for fluid under pressure comprising a containerhaving a neck, a cap on said neck, connecting means for securing saidcap on said neck, an inlet pipe extending from said cap, an outlet pipeextending from said cap, a pipe connected to the outlet pipe andextending substantially to the bottom of the container, a control valvein said outlet pipe having a portion disposed in convenient position foroperation, manually operable means for injecting air under pressure intosaid container through said inlet pipe, an inflatable and expandableelement mounted on said cap, said cap having a passage leading to thecontainer from said inflatable and expandable element for providingcommunication between the interior of the container and said inflatableand expandable element for indicating the air pressure within thecontainer and for relieving excess pressure therefrom.
